okay folks, i have two questions.

[1] i need to access memory outside the 64k segment my program uses
    at runtime.  in other words, i would like to be able to use ALL
    MEMORY if possible.  i have a large datastructure that requires
    the use of more than 64k.

[2] i need a method to reliably read the vga video memory by individual
    bitplanes.  i have been able to write directly tothe video memory
    but have not been able to reliably write to it.  any pointers?

i have a compag 386/25 with 5meg of memory.  source code examples in
pascal,c,or assembler would be greatly appreciated. i am using
borland languages for all three.

thanx in advance,
